    New chain and sprockets fitted today

    32,000 miles on this set, probably about 5,000 too many.  The chain hadn't stretched much and the rear sprocket looked ok (eSystem Scottoiler).  However the front sprocket had become hooked and the whole drivetrain was quite noisy.


    BMW in their infinite wisdom designed the front cover such that you can't check the condition of the teeth, which means removing the cover.

    My sprockets of choice are usually JT:  For the front I use the JTF404.17 and the rear the JTR7.45 in black.  However, there is a world shortage of the JTR7 in black, there isn't one in the UK (many are advertised, but none actually in stock).  The UK distributor said they are expecting some in the next couple of week. not much use!  I could get a silver one but baulked at the aesthetics!!
    The only other black sprocket I found was the AFAM.  When I came to fit it it didn't bloody fit!  As I'm going away on the XR next week I need a rear sprocket, so after much googling I resigned to going to the local BMW stealer to get an OEM sprocket for £86  :005:  + a set of sprocket nuts and a lock washer for the front sprocket nut.

    I used the DID GOLD ZVMX last time, so went for that again.

    Apart from the useless AFAM rear sprocket, it all went well - A Kellerman chain tool makes it all very easy.

    I think I would be happier with a plain steel sprocket than that chain that looks like it came from Ratners.  :004:

    I always go for black JTs too, if they don't have it I say "oh well it'll turn black from dirt in a week anyway" And so it does  :745:

    I bought a "silent" front sprocket for mine..:

    https://www.ebay.com.au/itm/282538145419?hash=item41c895f68b:g:saMAAOSwRgRfj95V

    And the rear is a 42T aluminium JMP job..:

    https://www.ebay.com.au/itm/403119831299?hash=item5ddbd07903:g:ofkAAOSwx2lbkwOI

    Chain is a DID ZVMX ....No issues with either so far and they have ~35k km on them and still look good...

    I run a "home made" electronic oiler system, does the same job as a $450 Scott-Oiler but only costs ~$30 Aussie sheckles and a couple of hours of my time..

    I cover about 15,000 miles a year and often have to complete journeys in the rain.  The gold sideplate chain is less prone to rust than the plain sideplate chain, that is why I use the gold chain. 

    As you didn't think before you posted this on a public forum, this is your "Ratner moment"!

    I don't mean to steal the tread, but I have a related question.  What size sockets are required for the front and rear nuts. I've replaced my chain and sprockets before, but my tools are at home and I am not. I'm on a tour and my setup has taken a sh*t.  I have a new chain and sprockets coming, but I'm going to have to buy/borrow the required tools. I think the rear is 34mm and the front I can't remember at all. Don't need to buy the wrong tools. Any help?

    The rear is a 34mm and this may help too.
